underside to the upper side of the bottom 24,- while its opposite ends are secured by means of brackets I! to the adjacent parts of the inner sides of the front and rear walls of the base, as shown in Figs. 1 and 3.

Within the base is arranged the resilient means which provide the yielding support forming part 7 of the cushion, and these yielding means include a plurality of upright helical springs 3|. The means for fastening each of thesespringstqthe bottom of the base preferably consist of a plurality of attaching loops 32 which are struck up from the bottom of the base and receive the lowermost convolution of the respective spring, a;s shown in Figs. 1, 2 and 3.

Above the group of springsand adjacenti to the marginal parts of the outermostspringsof this group a top retaining frame is provided whic h preferably consists of wire and comprises frontand rear longitudinal rods 33, 34 whicliare" fastened'totheouter parts of the upperrnost' convoluably effected-by means of-aclip A plurality of longitudinal-stay wires :40 are connected with the uppermost convolutions of i the several springs and the transverse rods 35 --ofthe top. retaining frame, anda plurality of transverse stay wires ll are connected with the uppermost convolutions of the severalsprings and the front and rear longitudinal rods 33 and 34 of thetop retaining frame, V W v f The numeral 44 represents a plurality ofupright stop lines-or flexible members which are preferably constructed in th'e'form of chains and are connected at their-upper ends at intervals with the severalbars or rods of -the top retaining frame, whiletheir lower ends are connected with the upper edge of the walls ofthe baseL The last inention'e d c'onnection is preferably effected through the medium of corrugated or crimped wiresp 45-which aresecuredlengthwise to the up per side of' the flanges 28 on'the base walls so as to form a plurality of upwardly projecting loop; to one or the other of which the lower-end of an 3 adjacent stopaline or-ichain may befsecured. I Thenumeral 46 represents additional stop lines or'chains which' are inclined and con'nect'ed at their upper rear ends with the inner parts of i the front springs at the top thereof, while their lower front ends are connected 'with i one or another of the loops of: the-crimped wire-45 'on' thefront part of the base in the same-manner in which thisis done with reference to the stoplinesor chains-44. V 1 1 r For the purpose of imparting an ornamental appearance to the front of the davenport, lounge or'chair the spr'ing cushion is provided on its upper front partwith one or 'more'shape bars o'r rods-5|, which, 'as shown in Fig. 1, are curved forwardly 'and connected by means of clips'52'or otherwise with the front rod'or bar 3301 the-top retaining frame. a

- a Inclined anti-swaying :bars or mass: are provided, each of whichis arran g'ed at ail-angle and pivotally connectedat its rear vlower endwith the bottom of the base by'meansof apivot hook 54 at its;rear end and engaging with a pivot loop 55 which is struck 'upfromthe add acent part" ofthe base bottom, as shown in Figs. 1 and 2. At its front end each of the stay rods or anti-swaying bars 53 is provided with an eye 56 which is bent around a downwardly projecting crimp 51 on one of the shape bars 5|. each of the anti-swaying bars is provided with a laterally projecting crimp or loop which interlocks with a crimp or loop 59 on the adjacent part of the front rod or bar 33 of the top frame,

A covering extends over the top of ltheresilient means of the cushion, which covering preferably consists of any suitable flexible fabric'or textile material similar to that now commonly in use' for upholstery work. This covering comprises an upper substantially horizontal sheet 60 which rests on the top of the springs, the top retaining frame, the shape bars and the stay wires connected thereswith; end flaps 61 extending downwardly from opposite transverse edges of this top sheet along the corresponding outer parts of the cushion and connected at their lower ends with the transverse flanges of the base; a rear flap .62 extending downwardly from the rearredge of'thetopsheet 60 along the rear part of the cushion and connected at its lower edge withlthe rear part l'of the base; and a front flap 63 extending downwardly-from V the edge of the top sheet 50 alongrthe front side The connection between the transverse walls and the rear .wall .of the base and the lower-edges of the transverse end fiapsand the rear longi tudinal flap of the covering is preferably effected by utilizing theichannel-shaped flanges. on the The intermediate part of corresponding parts of the .base for this purpose. 1

This is. accomplished by folding the lower edge, portions of .the rear flap and end flaps of the covering. around the lower edges of the correspohding1hodk-shaped flanges of the respective wallsvof the base,'as shown at l9 in Figs. 2,53, 4 and 7, then doubling the lower edge portionsyof each of these flaps; so that they engage with-the concave or inner side or channel of these-flan es, asshown at I8'qin the same; figures, and then clamping these, doubled portions of the covering flaps in'these channejls by means of ,clamping members ;having preferabl'ypthe form of bars vent disconnection of theseparts, while in use.

Whenthis spring cushion device is'assembled with the furniture. frame the underside of the several clamping strips GSengage with the shoulders or shelves 23 which are formed on the furniture frame bars or rails for the receptiontof thisjcushion, thereby confining these clamping strips within the channel-shaped flanges of the base walls and insuring a firm connection of thecovering flaps with the respective parts of; the base. 1

For the purpose of preventing theretaining strips or bars 65 from becoming detached from the channels of the base'when' the latter is not resting with the channeled flanges of. its wallson g the fiu-niture frame, locking means are provided which are preferably formed integrally with the walls of the base. In the preferred form of these locking means shown in Figs. 2-6 a locking lip 41 is stamped or cut out of the sheet material of the vertical side wall and then bent outwardly and upwardly so that the inner end of the lip remains attachedto the wall and the outer part bears against the underside of the retaining strip 65 and the doubled edge portion of the covering secured in the respective channel.

In order to permit this lip to be bent outwardly easily and conveniently by means of any suitable tool after the retaining strip has been inserted the area of the base wall immediately adjacent to the lower end and side edges of the slit in the wall forming the lip is deflected or dished inwardly so as to form a recess or pocket 48 in the wall into which the lip 41 projects downwardly and exposes its lower end and side edges before being bent, as shown in Figs. 5 and 6, and therefore permits a tool, such as a screw driver or the like to be inserted behind the lip preparatory to bending the latter outwardly and upwardly against the underside of the retaining strip and double'part of the covering, as shown in Figs. 3 and 4.

Other means may be provided for preventing a separation of the clamping strips from the base flanges, such as the punch marks or spurs 6B which are preferably struck out of the stock of the base walls in line with the channels of the hook shaped flanges, and engaging these spurs or indentations with the inner sides of the clamping bar or strip 65, as shown in Fig. 7, thereby positively preventing separation of these clamping strips under all circumstances, particularly'when transporting the spring cushions from one place to another while assembling the same with the furniture frames.

In order to avoid metallic engagement of the lower convolutions of the springs silencing means are provided which in their preferred form consist of strips 61 of burlap or similar woven or flex ible material placed upon the bottom of the base and between the lowermost convolutions of the springs and the next upper convolutions of the same, as shown in Figs. 1, 2 and 3.

This spring cushion is comparatively simple in construction, it has no parts which are liable to get out of order, thereby insuring maintenance of the same in a satisfactory and operative condition, and the same is also capable of being manufactured at low cost.
